Europe’s Ariane 5 rocket stands ready for liftoff from South America on Wednesday on another heavy haul into Geostationary Transfer Orbit with a pair of satellites for India and commercial operators Inmarsat and Hellas Sat.

Europe’s Ariane 5 rocket is assembled at the Guiana Space Center for its fourth mission of 2017 with the Inmarsat-S / HellasSat-3 multi-mission satellite in the upper position and India’s GSAT-17 C- and S-Band satellite in the lower payload berth.

The Indian GSAT-17 telecommunications satellite arrives at the Guiana Space Center for final pre-launch processing consisting of a series of ckeckouts including solar array and antenna deployment tests ahead of propellant loading for flight to be ready for integration atop the European workhorse launcher.
